Preparation method of normal-pressure low-temperature sintered silicon nitride ceramic riser tube
The invention discloses a method for preparing a normal-pressure low-temperature sintered silicon nitride ceramic riser tube, which comprises the following steps of: ball-milling selected ingredients to prepare ceramic slurry; aging and defoaming the prepared ceramic slurry, and preparing the ceramic slurry into ceramic powder; aging the prepared ceramic powder for more than 24 hours, homogenizing, and adding a forming additive; sintering the ceramic powder into a ceramic silicon nitride ceramic riser tube; processing the sintered silicon nitride ceramic riser tube to a designed size; and packaging and warehousing after qualified detection. The method has the beneficial effects of low production cost, large-scale production, good thermal shock resistance and the like.
本发明公开了一种常压低温烧结氮化硅陶瓷升液管制备方法，包括以下步骤：将选取好的配料球磨，制成陶瓷浆料；将制成的陶瓷浆料经过陈腐，脱泡，并将其制成陶瓷粉料；将制成好的陶瓷粉料经过24小时以上的陈腐以后并均化，添加成型添加剂；将陶瓷粉料烧结成陶瓷的氮化硅陶瓷升液管；将烧好的氮化硅陶瓷升液管加工到设计尺寸；检测合格后包装入库。本发明具有生产成本优势、可大规模生产和抗热震性佳等有益效果。
